摘要:
An image processing apparatus receives color data and includes a masking processing circuit for modifying the colors represented by the color data by processing each of the different color data received. The colors are modified according to other color data associated with each of the colors represented by the color data. The masking processing circuit includes a first memory for storing data representing each color and a second memory for storing data from the data derived after masking processing the data stored in the first memory. The color data and the other color data are used as addresses in the first and second memory. The number of bits of each color data used as an address for each respective color is larger than the number of bits for each of the other color data received at that portion of the memory.

A color image reading apparatus having a color sensor with plural sensor groups, the color sensor for separating an objective image into plural color components and for converting the plural color components into plural color component signals, and a shading corrector for performing shading correction for the plural color component signals. The shading corrector causes the plural sensor groups to substantially simultaneously read a reference plate and automatically corrects a shading correction state for each of the plural color component signals in accordance with data obtained from the plural sensor groups.

An image processing apparatus is provided with an input circuit for inputting a plurality of multilevel signals, each corresponding to a respective one of a plurality of pixels. An emphasizing circuit emphasizes a high frequency component of one of the multilevel image signals by using the multilevel image signals of a plurality of pixels and outputs the emphasized multilevel image signal. A discriminator discriminates a dot area of an image represented by the one multilevel signal input by the input circuit, by using the multilevel image signals of the plurality of pixels whose high frequency component is emphasized by the emphasizing circuit. The number of pixels used by the discriminator is larger than the number of pixels used by the emphasizing circuit.
